Energy technology
More energy on every planet: +1% per level – and a requirement for many buildings, research and defenses.

Effect
Each level of Energy technology increases the energy from Fusion plant, Thermosolar plant and Solar cells by 1% – on all planets. On the Economy page the bonus appears as a separate energy line.
Key to the tech tree
Early on, what Energy technology unlocks matters more: Weapons factory (level 1), Mining technology, Shield technology and Thermosolar plant (level 4), Targeting systems (level 6), Microsystem accelerator (level 10) and many defenses from Light graviton cannon to Solar cannon.
Later on, each additional level pays off mainly if you have large power plants or lots of solar cells, because the bonus grows with your energy production.
Background
Energy technology is a highly important factor in the development of high-performance machines. Energy efficiency should reduce costs to a minimum size at a minimum level of use. Every level increases the efficiency of the energy conversion by 1%.
